Now I expect a video on cans. From the hard soldered ones, that could be quite dangerous if done improperly, through the war year ones, to the modern ones with liners that essentially eliminate problems with botulism. And all the rabbit holes to square cans, flat cans, integrated openings, whether key, pop top, etc, to the self heating cans for military, and survival use. Easily another video or two in there.

_"Fun Fact: Ever since I was a small child, my parents had a Black & Decker electric can opener in the kitchen which was called 'Grand Openings'. Maybe THAT'S why I'm like this."_ I LOLed. I LOLed hard. Anyway, I've been using rim-cutting can openers at least since 2000. If anyone is still using the old kind, it's purely because they already had one, and can openers don't wear out. The only problem I've ever noticed with rim-cutting can openers is they tend to skip over dented spots on the rim, which can make removing the lid from a dented can difficult.
Silent Ferret

@fashnek No people do buy same brand can openers if they can find them. Black and Decker still make electric can openers and a few brands that made old hand powered openers still make them as well. The tolerances for can openers have gotten sloppy so they don't fit as well and the cans themselves have gotten thinner on the lip so the old ones will slip more than they use too. I think the cans changing might have cause a lot of can openers to go to the garbage cause they used the old fitment style cause I had even brand new ones slip and they were not cheaply made.

@Bobo I have had all metal can openers old and new and they wear out or deform from use and get sloppy cutting. Its not even being plastic as most the times its just decorational caps or fill which on most do not affect the function.

@fashnek You're wrong. Just modern, if I may say so, can openers are made by marketers for planned degradation: how else to sell new ones? Our family "can knife" was produced and bought by my grandfather sometime in the mid-thirties. It survived many file sharpenings and thousands of cans, starting from canned goods of the USSR, continuing with lend-lease British cans and ending with modern, relatively thin cans. Perhaps this has something to do with the absolute absence of any moving parts, just two "claws" for different types of cans (or glass bottles) and a riveted eyelet between them. P.S. BTW, it is also far superior to both so-called modern designs. Weird bottom? No problem, the knife's focus always falls on its ring, on the top of the can rim. Really thick steel of the Soviet-era cans, on which both of these designs will either not work at all, or will require impossible efforts on the crank? No problem, the lever principle on which this design is based helps perfectly! Is the cutting surface blunted? Sharpen it with a file and be happy... Or just apply a little more force, remembering the previous point. Do you need to open a bottle of beer or a three-liter jar of cucumbers? No problem, just turn it by 180 degrees, and use it for the second intended purpose. And also - the Soviet design of the thirties is compact, light and can be run over by a car without any harm to mechanics and usability, for lack of the first and robustness of the design for second.

as an older person I had a hard time with traditional can openers, so I tried the side (seam) cutting can opener. it is easer on my wrist and hands, cuts clean and with little effort. I find it to be very effective. This is coming from a mechanical designer with over 40 years experience. I highly recommend this for older people, or people with medical issues.

13:33 - these can openers have internal mechanics that will give out far quicker than the lever on a standard can opener. My parents have stripped four of them already, meanwhile the can opener from my childhood sits in the drawer unused because my mother lacks the hand-strength to lever it. However, it IS the one that comes out for tuna fish sandwiches as the newer style of can opener does not lend itself well to the straining of can contents by pressing the cut (and prewashed) lid down and into the can to press out the tuna water/oil.

@Me Here Not being able to eat alliums or tomatoes, I understand the challenge. That having been said, it wouldn't be that difficult to make a vegan meal plan with no wheat, nuts, or legumes - legumes being the most difficult to replace and also the reason why I still use my non-safety can opener. (As well as canned tuna, chicken, etc for the family.)

I just fold the lid a bit across the center line, then it is smaller than the can along one dimension and no chance of the edge cutting your hand when squeezing the juice out.

@Don Robertson This is the reason fish farms exist and tuna companies work so hard to use dolphin safe fishing practices. You're also not considering that canned tuna is the cheapest low fat protein source that millions of poor families depend on. Yes, vegetarian and vegan diets are a thing but they are often cost prohibitive and require supplementation to maintain health. That combo puts them out of reach for the poor. I can appreciate your compassion for the animals but it would serve you well to remember that humans are also animals and also deserving of that same compassion.

I've had one since the 90s and it still works fine. It opens every can I ever tried. My favorite part of owning it is watching other people who aren't aware of this type of can opener try to use it. The 25 seconds of ensuing chaos and confusion is fun every time.

@The Forge Master Yes it is there, but way attenuated compared to "realistic" levels, because of his shitty microphone setup (which is quite obvious, given how faint the sounds was from the cans and can openers as well)

@Speeder84XL Yeah, there is a whole science to it. No wonder "sound engineer" can be learned here in Germany as a university degree, or as sound technician in a 3-4 year apprenticeship. (The university part has some more theory while the apprenticeship of course is more hands one. I would mind neither doing the job, as both are usually highly skilled.) And then there are even specialties if you are studying movie arts, where you can delve into those specialized realms as well. And while I know some through reading and doing, I would put myself at best on a lower amateur level. Also I am less in videography than still photography. And neither was part of my computer engineering studies, although, working with telephony systems, I get into the nastyness of microphones and speakers in form of head sets more often than I like.
Speeder84XL
Speeder84XL ヶ月 前
​@Alexander Kupke It's different if you intend to do some sort of a mix that can't be done from one spot to get all sounds you want. But for filming, the best viewing/listening experience is usually to have the microphone close to where you would have you are ears if standing at camera position (perceived position actually - so, if a telephoto lens is used, the mic should ideally be closer than the camera). Best setup is in most cases, is to use 2 omnidirectional microphones in stereo with 34-37 cm between (that will give a sound very close to "binarual recording" without the need for a complicated dummy head setup. Also the greater spacing, compared to typical ear distance, will give better stereo perception when played back thru speakers, without sacrifice much of the listening experience thru headphones). Directional mics could be used in some cases - but those have a very poor low frequency response that makes them quite useless as high quality camera mics. The specifications for such mics, often shows they have a linear response all the way down to 20 Hz, but that's (due to the their acoustic and physical properties) usually only valid for close range recording at a certain distance (often not more than 60 cm from the sound source). Any closer than that it will have too much bass (which most studio people are well aware of. For example pod casters like to use it, to make their voice more "bassy", 🙃). But, further away, the bass is attenuated by quite a lot instead (which makes them poor camera microphones).

My example of amazing improvements since I was a kid is the new design of scaffold connectors, replacing the split pin and toggle with a post and locking bar design. Vast improvement. The old design would get jammed up with dirt or paint and soon require a hammer to move. The new design can be fished on from several feet down the diagonal cross rod.

I can still remember my first time using one of these. It was at a restaurant I worked at. They had a mounted can opener on the table back by the sink, like it's a whole thing that clamps down and was screwed into the table. I was told to get some tomato puree, big can, size if my head. I am using this thing and feel like I'm not cutting anything the whole time, there's a knife on the bottom of the can opener like old ones and is intended for opening juices. I literally just stabbed the can open with that thing, probably the most jagged and unsafe can opening you will ever see, all because it didn't feel like it was cutting lol. Felt really dumb when they showed me how it worked lol. Everytime I saw that can in the walk in for the next week I saw evidence of me just going full ape.

We've had one of these for years! It's actually a clamp-style like traditional can openers, but it cuts the seam rather than the interior of the lid. It also has a tiny grabber for the lid that's near-useless.

Now on a video about can openers, I think there are three methods worth mentioning: 1. taking a regular roundblade opener (like in 3:28) and turn it horizontally, letting the blade run on the outside of the can and the counterwheel on the inside of the lid. That pops the head off of the can which admittedly leaves a sharp edge on the top of the cylinder, but it's a good alternative when the regular way does not give you enough grip. also helps with situations like 9:37 2. the repetitive punctuation method with the can opener tool of a swiss army knife 3. no tools: simply bending the can back and forth at half the height of the can until it becomes weak and brakes in half

Got one of those as a kid and the thing I remember is it had trouble with cans that weren't completely round. If there was a dent, then it would have trouble. It also didn't last very long before it broke. I think the mechanism that pulls the drive wheel in can wear out quickly, at least with the one we had. The traditional double wheel is much more reliable of getting the job done. Hopefully they have improved over the last few decades.

Interesting thing, I seem to encounter mostly the pullopen type things here these days but I couldn't find my can opener a few months ago and still haven't gotten my own after borrowing one from my neighbour briefly to open the can on that day. I think I'll try one of these contraptions first to see how I like it, they aren't that expensive and also a bit more compact in the kitchen drawer.

When I was a teenager, the lawnmower my parents owned had a self propelling feature which didn't work. This made the lawnmower a heavy push mower. The need for a replacement wasn't very high for my parents despite my complaints. This one worked just fine. When I moved out, however, they promptly bought a riding mover.

What happens when the rider’s transmission goes out? Then you’ll have a really really heavy push mower? But seriously, a self propelled mower in good shape is very easy to deal with after training half your life with the extra weight of a failing self propelled. I once used my neighbor lady’s mower, a normal (gas) push mower and it felt so light and free rolling compared to my dad’s with worn down tires that wouldn’t engage the metal drive things.

This fits oddly well with the side discussion: “I’ve come up with a set of rules that describe our reactions to technologies,” writes Douglas Adams in The Salmon of Doubt. 1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. 2. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. 3. Anything invented after you’re thirty-five is against the natural order of things."

When I moved out of my parent's house and in with friends, I went from using a classic can opener to a "safety" can opener. For ten years I took for granted that when I open a can, the lid won't fall into the food and have to be fished out, and can be used to re-seal the can for refrigeration lasting at least a couple of days. Then I helped my mom make enchiladas back at home and used a classic can opener again. This video has motivated me. I'm going to inventory what kind of can openers everyone in my family use, and if they don't have a "safety" style one, they're getting one as a gift this year.

@Mr. Popo You're right, I dont NEED him to do it for me at all. I think id prefer not to spend time critically thinking to find ways i can open a can slightly better. This stuff isn't life changing.

Why watch a review of a product? just do some critical thinking instead of letting someone else do it for you.

I used to have a "side-cutter" that still had two handles that you had to close together to make it start cutting - same as a top-cutter. It did not have the automatic clamping that yours has. Why is that better than yours? Two words...LEFT HANDERS. Because mine was completely ambidextrous - it opens the can identically whether you clamp the handles together on the left or the right side of the can - and whether you turn the handle clockwise or counter-clockwise. Sadly, it did eventually wear out - and I have yet to find a replacement.

I've seen a tip for 'standard' manual can openers that you can usually place the opener at a 90 degree angle such that you are cutting the SIDE of the can rather than the top of the lid. this prevents the lid from falling in, although the sharp edges remain.

When I found your channel I was amazed at how you had the ability to make a 25 minute video about detergent in dishwashers interesting even for your target audience of curious people. I was pleasantly surprised at not 1, not 2 but 3 video essays about Christmas lights. So I don't know why my first reaction at seeing the title of this video was "has he gone too far, is a 20 minute video about can openers really needed?". I'm sorry I doubted you. This was great.

The tapered top of the "chunky soup can" allows nesting when they are stacked on the shelf. I learned this when trying to stock shelves of cans that were the same diameter on top and bottom.

what surprises me most is that his can is slimmer at the top. I've only ever seen it done at the bottom, with the rim practically as wide as the can itself, just so that it fits inside the other side.

Perhaps it's a Europe/America thing, but I've only ever seen cans with the taper on the bottom. I normally open the bottom of cans because it's easier to get the contents out if it's something like baked beans or a chunky soup, which means tapered and ring-pull cans go in the cupboard upside down.

One example of this I always found kind of amazing is that bar codes were invented about 10 years before lasers. They predate even the *theoretical* existence of the thing we use to read them! (For the pedants - the bar code was first proposed circa 1949, the first legit patent I can find was in 1953. I believe the expectation was that they would be read by conventional optical sensors, but this was unreliable in practice and the whole concept wound up largely abandoned as a result. The first working laser was built in 1960, based on theoretical work dating back to around '57. That work was an extension of the somewhat older idea of "masers" which used microwaves instead of visible (or near-visible) light. The two technologies were finally united when the UPC system was developed in 1973 (pat. 1974) by George Laurer at IBM.)

I've been using a smooth edge can opener since the 90's. Still actually use the one my family got when I was a child. Fearing the day it wears out as the modern ones do not work as smoothly.

My mom bought one of these back in the 90s when we visited Hong Kong. For me as a kid, it blew my mind. I didn't know it was invented in the 1980s! That can opener she bought was the only one of this kind we ever had, for many years. While at first I messed up some cans with it because I didn't know how to use it, I ended up figuring it out pretty quickly, and I used it regularly when living on my own in college. We don't have it anymore, because sometime in the last decade the cutting blade got dulled to the point where it just wouldn't really open cans effectively anymore. But we have yet to buy a replacement of this same type, which has always disappointed me. I fully agree with you that this is a superior design. It eliminates sharp edges, and I also love being able to put the lid back on the can and stick it in the fridge. I would love to get one of these for my next can opener (lol these things take a while to get used thoroughly...and now I'm thinking about how I've been planning for years to replace my car with a hybrid or EV except for the fact that my current car still has usable life in it). One thing I didn't see you address was some apparent "glue" between the lid and the can that sometimes shows up in the cans I open. I don't know whether it's actual glue or just food residue that's gotten stuck in the pressed portion and dried up, but for some reason there's sometimes a little bit of rubbery-looking stuff between the lid and the can when I open it with this style of opener. But it's always on the outside of the can so it's not really an issue for me.

Thanks for the revelation! The safety can opener is something I've never seen. Shall be buying at least one soon. But a couple of refinements to it would help greatly: 1) Give it a longer turning lever to reduce the force required to use it. 2) Adjust the cutting head geometry so that it can be used left-handed as well as right-handed. 10% of people are left-handed, and quite a few others have a weak or missing right hand. --- That's it for the safety can opener. For those who choose to read this further, about can openers in general, the following are some related points raised by the video. A useful tip: Attach a small Neodymium magnet to the tip of a conventional can opener, to allow the opener to lift off the cut lid from a steel can. No more fishing around in the top of the can when you don't stop cutting soon enough. It also lifts any small metal fragments which (rarely) drop into the contents. I've used magnets glued onto openers since about 1980. Why don't manufacturers add a small magnet, or magnetise the can opener itself? It's a simple and low-cost improvement. You're using the wheeled can opener backwards. I've never seen them turned that way before. Might try it. Another useful tip: The wheeled opener can also be used to cut around the side of most cans, removing the lid with no sharp edges, and allowing easy removal of all contents. The downside is that the top of the can now has a sharp edge. I've almost given up trying to use ring-pull cans. Most of the rings break off, sometimes leaving me injured, and a partially opened can which then needs opening with a pair of pliers. (I once cut myself badly when a fish can ring pull failed. That required a visit to the hospital and 15 stitches, including repairing a severed artery.) Not ideal. So I almost always use a can opener instead of the ring pull. If the can has turned-in top and bottom edges along with a ring pull, I simply don't buy the product. That said, some cans do have well-designed ring pulls. As for his hair, that's his choice, and I can live with that. If not, then I wouldn't be watching the video. Most of us have no right to tell anyone to change their preferences. Suffice it to say that, in certain walks of life, and in current times, hair like that can attract the wrong kind of person, if you're not looking for men.

I remember watching the commercial for these back in the 90s. I have a feeling the major flaw was the way it was marketed. I remember the commercial focusing largely on the safety aspect and I remember thinking it just made the can sharp instead of the lid. Rewatching it now that doesn't seem to be the case. I think your evaluation that "we already have a can opener, just be careful" is spot on. jpvid.net/video/%E3%83%93%E3%83%87%E3%82%AA-g4NkPcEhvaQ.html

So I am super late to returning to this channel for regular viewing (probably) but I absolutely love the point made in this video! Some things are the status quo because they are the best option, but sometimes we have an opportunity to *improve* the status quo and not just accept something suboptimal because it's everywhere. That's the kind of principle I'm really devoted to as a young (and probably naïve) adult

17:27 Unless you're in your teens or early twenties ... almost everything. You get used to it and the struggles of life have you worn down so much that striving for optimization of even the smallest things is a struggle. Why change what works, why seek the better when what is here now is fine, is usable and above all - is something you're used to? Mind, I agree. We should seek the betterment of things. Even something as small as where a menu is in a program we use - maybe it actually makes more sense in that new place and it's our own mental inertia that makes us grumble at change. But I'm getting old enough to start grumbling myself because it takes more TIME to learn new things as I age. It takes more ENERGY to adapt to new ways. It takes me out of the (semi) comfortable life I have and puts me in a place where I have to devote effort to just do the same damn thing I've done a million times before but 'now it's over there or with that motion instead of this one and why the hell do I have to figure this out, just let me do the stupid thing' ... Anyway. Nothing important, nothing major here. Just some rambling thoughts on the big social question you're asking. Age makes grumbling old folks of us all.

9:00 When I got a "safety" can opener for the restaurant I work at, my main reason for doing so was that the cooks could get a spatula in the cans to get more product out of the cans without the burrs left by traditional can openers slicing up the spatulas. A can opened with a safety opener is far less likely to damage a rubber spatula and cause physical contamination concerns.

My parents got a can opener similar to that one when I was growing up. It was touted as a "safety can opener" since it left a rounded edge on the lid. It had a "squeezing" mechanism like a normal can opening to bring the teeny cutting wheel into contact with the can (instead of the simple rotation grabbing the can like yours). I wonder if that was a change made to make it seem more familiar to people used to the Danger Can Openers. In other news, Toxic Midwestern-ness is a hilarious concept to me as a Nebraskan Millennial. The heat pump conversation is VERY familiar when discussing technology that "I don't need to bother with it, I tried it already and it was bad". As always, thank you so much for your videos. Your writing style is goofy and entertaining, and I always look forward to new releases. Thank you for sharing your time and talent with us :)

@Omer Magen Aaah! Ok, so it is the "German can opener"! 😂 The plow part, the upper part of the spade, responsible for "the opening" isn't even sharp! So, basically it just pushes the metal to the sides... it does not cut or slit... nope, just mushes the tin and some zinc plating rubs off from the cans rust proof inner layer and form clumps of zinc, zinc dusting, zinc goo along the gouge the spade/plow leaves behind! The plow isn't even asymetrical to tend to stay near edge of can, no no, it can sometime take a heading more inward towards can center! But, it stays usually within about 1-5mm of can edge. Geez! The much simpler "swedish" (nordic?) opener is dangerous/prone to stab you if you rush it... which you always do because it only opens 3-4 mm per full stroke so it gets tedious. Ramming the German spade thru the lid definitely takes some effort and is not exactly confortable to hammer with a bare hand (if you do proper work with your hands daily its no problem, but I doubt many more than 10-15% of women would be able to cope with it without more tools).

Opens cans and hands in any demands! 😂 I found a worse one (or I actually need the instructions). The german opener: it has a vertical "V" pointed spade you need to ram through the lid from top. That spade is on a swiveling plate riveted to the handle. The handle has a series of small agressive shark fin tooth in a radius that gets traction on the outside of the rim. Then you drag the spade/swivel plate behind the handle when it feeds forward. Like a (dull) plow it works its way thru/around the lid while the handle bites into can outer rim. I hope there is a smarter way to get the spade through than the brute force i use 😂 technically i do not know if my opener is infact "the german can opener", it was the only one available to buy in the village store.

17:24 Light switches. Traditionally (with the exception of a 2-way switch) you flip them UP to turn the lights ON but not always in other countries. We have a 2-way switch at the bottom of the stairs that turns the upstairs light on BUT when you get to the top, you flip the upstairs switch in the opposite direction of the downstairs switch to turn the light off. This reverses the downstairs switch. If you go back down without turning the light on the whole damn system is backwards.

I’ve got one of those several years ago, and when I initially got it, I was utterly confused as to how to operate it. I ended up just throwing it in junk drawer where it sat for like 2 years. About a year ago, I could not find my Swiss Army knife for can opening, and had to figure out this can opener, poked around for couple of minutes, and exactly as described: felt like I was not making any progress at all. And then the lid came off in the cleanest way possible, that was mind blowing experience.
